9bb149ca13 Bugfix by Raimondas Sasnauskas: TCP SYN duplicate receptions in the SYN_RCVD state was not correctly handled 2010-02-15 18:03:07 +00:00

d67d1f7340 Major bugfix, found by Raimondas Sasnauskas: the TCP periodic timer was not started when a new connection request arrived. If there were no other active TCP connections, this means that the SYNACK would never be retransmitted, potentially leading to a forever stale TCP connection. 2010-02-09 12:58:53 +00:00

671216c558 No need to clear the headers now that we explicitly save a queuebuf when sending fragments 2010-02-06 17:07:43 +00:00

b6647b5630 Turns out that with cxmac, clearing the header after sending a packet is not enough to make fragmentation work. Instead, we allocate a queuebuf and restore the packet after from the queuebuf after sending it. 2010-02-06 09:42:49 +00:00

494e692d0b Bugfix: clear the header after sending a packet solves a problem with fragmentation; also prod the watchdog since fragment transmissions can take a long time with some low-power MAC protocol 2010-02-06 07:49:58 +00:00

4bffd277f5 Don't set the stream bit on outgoing TCP packets for now - it doesn't seem to play well with IPv6 and X-MAC 2010-02-03 16:44:19 +00:00

181213124b Added a configuration option for setting the MAC channel check rate (which must be a power of two). The configuration is independent of the MAC protocol. 2010-02-02 23:28:58 +00:00

1a13d25d33 Revised version of the X-MAC implementation that uses a ctimer instead
of an rtimer for the periodic radio duty cycling. The benefit of this
implementation is that it leaves an rtimer free for user tasks. The
drawback is a slightly higher idle power consumption. This new version
is based on the current rtimer-based X-MAC.

7615a6cf47 Bugfix by Henrik Mäkitaavola: check that ICMP6 process is defined before invoking it 2010-01-25 13:37:05 +00:00
adamdunkels
4f3e8d565c Added a simple CSMA (Carrier Sense Multiple Access) mechanism that
works on top of an underlying duty cycling mechanism. The CSMA layer
retransmits packets that could not be sent because of a collision was
detected.

7ad93e5d18 Added a field to the struct mac interface:
channel_check_interval(). This function returns the interval by which
the duty cycling mechanism checks the radio channel for activity. It
is used by higher layer mechanisms to determine suitable timeouts for
retransmissions.
